Question

Determine by substitution, if :
a) 2 is a root of 5x -10=0​
In detail please

Answer 1

If we have to verified then,5x - 10 = 05x = 10x = 2and if we put the value of x = 2in LHS then we surely get 05x - 105×2 - 10= 10 - 10= 0

Answer 2

Answer:

$x = 2 \\ \\ 5x - 10 = 0 \\ 5(2) - 10 = 0 \\ 10 - 10 = 0 \\ \underline{ \underline{ 0 = 0}}$
